Abstract
Decision support models are created to help decision makers evaluate the consequences of various management alternatives. To be most useful, the decision support model should also include information on the uncertainties associated with each decision option, since certainty of the desired outcome may be a key criterion for selecting a management action. In addition, an otherwise attractive management approach may also be associated with an increased likelihood of an extremely undesirable outcome, and the decision maker may prefer to choose a different decision option that reduces this risk, even if the expected benefits would also ecrease. In order to evaluate the reliability related to certain information and the assessment that a decision support system provides to the captain, it is essential to understand and quantify the associated uncertainty. For the design of a safe ship, it is necessary to evaluate the reliability of seakeeping analysis and wave load estimation as well as operational conditions under which the ship is expected to perform its mission. The same uncertainties are associated with the procedure of attainable speed prediction. However, these uncertainties are strongly coupled with the uncertainties of the engine and propulsion system performance, as well as with officer on watch judgment.
